5.3 and HT with SMP
How stable and successful is HT support via SMP? (I presume it is supported) I have a P4-3.06 with HT support I had a 5.3 machine with an HT/SMP kernel (no other customizations) and the server would randomly reboot. Could be a few hours or could be a week. I setup a new machine (same exact model and hardware) and installed 5.3 again on this machine and the same thing happened. So thinking it was the network, I disconnected the ethernet and still it reboots within some time. I then ran a debug kernel and it ran for weeks with no crash. When it did crash, there was no logs and no errors. The servers are on a huge stable UPS. Solaris runs on these machines for months. Anyone see this? anyone have any ideas? -- J.D.

Also, make sure you have crashdumps enabled (see handbook and developers' handbook for more details), because your "randomly reboot"ing may actually be the server panicking because of a kernel bug.

This bios is right up to dateso unless there is some fix out that has not been releasedI am at as high as I can be. Also, make sure you have crashdumps enabled (see handbook and developers' handbook for more details), because your "randomly reboot"ing may actually be the server panicking because of a kernel bug. I had crashdumps enabled and since the machine never crashed even after 2 weeks I Was unable to capture anything. I wanted to add that I had never had any issues running 5.2.1 on this machine even with the same bios. So I am left to think something changed in 5.3 that somehow now I am hitting. I cannot rule out my scsi cards/drives...so this week I will be doing a new install on this hardware with IDE only and then see if anything changes for the better. although as I stated before..solaris runs on these machines for a very long time with no unexpected reboots Very hard to find out this error!

I'm running 5.3 RELEASE now on a P4-3.0 with HT support, and it's fine. I assume there are no log entries in /var/logs/messages? And, are you running a generic or custom kernel? > -- > J.D.

I was running a custom kernel...so I rebuilt the generic kernel and it still rebooted I will be trying this again..fresh install (no custom kernel) and IDE. If it still crashes, I will be asking the group for some help..I can even hook a laptop up to the console to capture things 24/7 if needed. 5.2.1 was rock solid. Although 5.3 performs better overall :) -- J.D.

Re: 5.3 and HT with SMP
on a general note (as a newbie) what's the recommended setup for HT? right now I have it disabled w/ 5.3 GENERIC and I haven't seen any strange behavior. should I try enabling it and switch to the SMP kernel? thanks, g. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
